[Qemu-devel] [PATCH] Name the default PCI bus "pci.0" on all architectures

[Daniel P. Berrange]

The system emulators for each arch are using inconsistent
naming for the default PCI bus "pci" vs "pci.0". Since it
is conceivable we'll have multiple PCI buses in the future
standardize on "pci.0" for all architectures. This ensures
mgmt apps can rely on a name when assigning PCI devices an
address on the bus using eg '-device e1000,bus=pci.0,addr=3'
